Was there a kernel update? Sometimes the new initrd does not support dmraid. If this is applicable, boot into the old working kernel and run mkinitrd against the new kernel, reboot and x-fingers. This has worked for me in the past.

My 18 yo kid has an ich5 Raid0 dual boot of Winxp/Fedora going for almost 4 years. Once when updating the kernel it was necessary to rebuild the initrd.
